This line of code is wrong

url(r'^$', views, hello_world)

You just imported the view which is the file view.py. Now you need to call the function view, which it is going to be like:

url(r'^$', views.hello_world)

And you might think it is going to be useful to give that url a name so you can use it as a reference in your templates in the future.

url(r'^$', views.hello_world, name='hello-world')

Also, you can import your view.py as follow:

from .views import hello_world

The next is possible as well as suggested in the comments Niayesh Isky, but not encouraged.

from .views import *

The error is telling you that there is no variable such as hello_world defined. You need to change it to:

url(r'^$', views.hello_world)

Where views is the views module that you have imported at the top.
